We would like to introduce a case study of the development of fasteners proposed by Yamaki Sangyo for securing cement flat roof materials to fire-resistant sheathing. The customer's request was to secure the roofing material to the fire-resistant sheathing. Since the substrate is made of inorganic material rather than fibrous material, there was a significant issue with fasteners being prone to pull-out, and there was concern that if the head of the fastener was not flat, the roofing material would crack when walked on. Therefore, we proposed using screws instead of nails. Additionally, we used a special flexible material with grooves in the washer part of the screw to ensure that the screw head is flush with the material. Through these innovations, we were able to propose a screw that meets the customer's requirements. 【Case Study】 ■ Issues - Fasteners are very prone to pull-out when secured to inorganic materials. - If the head is not flat, the roofing material may crack when walked on. ■ Proposal - Use screws instead of nails. - Use a special flexible material with grooves in the washer part of the screw to ensure the screw head is flush with the material. *For more details, please refer to the PDF document or feel free to contact us.

Our company offers a variety of cleverly designed fasteners. The "Namiitabisu" is used to secure wave panels made of reinforced plastic (polycarbonate) to aluminum or steel frameworks. The screw itself is equipped with a stopper that matches the height of the wave panel, designed to prevent rain leaks caused by insufficient driving or deformation of the washer and wave panel due to overdriving. In addition, we have developed various products such as the "Bestreamabis," used for securing fire-resistant sheathing to C-shaped steel, and "Double Head Nails," used for temporary fastening. 【Features of Namiitabisu】 ■ A stopper on the screw that matches the height of the wave panel ■ Design that prevents rain leaks due to insufficient driving ■ Design that prevents deformation of the washer and wave panel, which could cause rain leaks due to overdriving *For more details, please refer to the PDF document or feel free to contact us.

Screws and nails are important not only for their functionality but also for their appearance. When considering the finish of screws and nails, the key points are "surface treatment" and "shape." By applying surface treatment (such as painting) mainly to the heads of screws and nails, their appearance can be improved, or by matching the color to the material, the heads of the screws and nails can be made less noticeable. Conversely, there are cases where items like decorative nails, tacks, and chrysanthemum nails are used to stand out (by adding decorations). [Key Points] ■ Surface Treatment ■ Shape *For more details, please refer to the PDF materials or feel free to contact us.

When fastening screws or nails to objects subjected to shear forces, it is necessary to use those with high strength. Two points for selecting strong screws and nails are "shape" and "material/surface treatment." While increasing the thickness of screws and nails is one way to enhance strength, it is essential to consider various conditions, such as situations where it may not be possible to make them thicker due to the nature of the worksite.

Corrosion resistance is a very important point in the selection of screws and nails. One method to enhance corrosion resistance is surface treatment. Surface treatments include electroplating, where metal is deposited on the surface through electrolysis; hot-dip galvanizing, where metal is melted and coated like a garment; and painting, where resin or metal powder is applied. In addition, material and galvanic corrosion are also key points in selecting screws and nails with high corrosion resistance.

To improve work efficiency, it is necessary to consider various factors for each site where fasteners (screws, nails) are used, ensuring that tasks can be performed easily, quickly, and with one less step, depending on the objectives. The two key points for enhancing work efficiency are "connection" and "shape." Using the same screws or nails, connecting them for machine fastening allows for one-handed operation, rather than manually hammering or tightening them individually. Additionally, there are methods to make products less likely to come loose by changing the shape of the body part through processing.

When using screws or nails in conditions where they are likely to come loose, it is particularly important to pay attention to holding power. There are three key points to maintain holding power: "surface treatment," "shape," and "special products." One method is to apply a special chemical to the surface of the product, which acts as an adhesive to prevent loosening and slipping. Another method involves changing the shape of the product's body to make it less likely to come loose. Additionally, there are methods that involve combining the product with other materials or shapes to achieve a loosening prevention effect. [Key Points for Maintaining Holding Power] ■ Surface Treatment ■ Shape ■ Special Products *For more details, please refer to the PDF materials or feel free to contact us.
